CAR-JOURNAL BEARING.

SPECIFICATION forming' part of Letters Patent No. 591,808, dated October 19, 1897.

Application filed February ze, 1897. seal No. 625,076. (Numan.)

To @ZZ whom it may concern.:

Be it known that we, WILLIAM RUsHToN Bowxnn and JOHN RUsHToN BowKER, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Car-Journal and Locomotive Bearings, hereinafter called the journal-box, of which the following is a specication. A

Our invention relates to improvements in car-journal bearings; and the object of our improvements is to provide a continuous lubricated bearing for the journal. Ve attain this by the mechanism illustrated in the accompanying drawings.

Figure l is a front view of a journal and bearing with our improved lubricating devices shown in dotted lines. Fig. 2 is a longitudinal vertical section through Fig. 1, showing one of the lubricating devices, which will be hereinafter termed wave-breakers. Fig. 3 is an end view opposite to Fig. 1. Fig. 4t is a horizont-al section showing two of these wave-breakers located in diagonally opposite corners of the bottom of the journal-box, and Fig. 5 is a section on the diagonal line 5 5 of Fig. et.

A is the j ournal-box, having the end bearings D D, and B is the journal. The bottom of box A forms the oil-reservoir.

In the bottom of the box or oil-reservoir we place or form, preferably in diagonally opfaces of these breakers or detlectors O C till it reaches the upper overhanging edges, whereupon it will break into spray or splash upwardly upon the journal, the surplusvoil falling back into the reservoir. It will be seen that this is a very simple and inexpensive means foi-lubricating journals and their bearings, and it is not to be confused with wings or flanges projecting over a reservoir to prevent the oil from escaping therefrom.

XVhat we claim is- 1. The combination, with a car or locomotive journal-box the lower portion of which constitutes an oil-reservoir, of one or more wave breakers in the said reservoir and shaped to break the oil-waves and splash or spray the oil upwardly against the journal, substantially as described.

2. The combination, with a car or locomotive journal-box the lower portion of which constitutes an oil-reservoir, of one or more wave-breakers located in the corners of the reservoir-bottom and having concavities or inclines to force the oil upwardly toward the journal and overhanging' edges at the upper ends of the concavities to break the waves and cause the oil to splash or spray upwardly onto the journal, substantially as described.

3. The combination, with a car or locomotive journal-box, the lower portion of which constitutes an oil-reservoir, of breakers located in diagonally opposite lower corners of the reservoir and having their opposed faces concaved and terminating in overhanging edges to break the ascending waves of eiland splash or spray the same upwardly against the journal, substantially as described.
